Restrain them to an operating table.
Use a scalpel to cut out the skin on their sides. Now rip out there kidneys with your bare hands, making sure to dig deep in their body, ripping veins and all that stuff. Now, pour some lemon juice on it, making sure it is at least 2 PH. Next, cut off their genitals quickly, whacking them with their own manhood, humiliating them. Keep doing this till they sing mercy in the highest tone possible. After that, remove one of their lungs, making sure to do it slowly, then pouring more lemon juice on to all the wounds. If they try to resist or fall asleep the hole time, use a stun gun on them. Now, to finish them off, take a knife, and cut a hole in their skull. Slowly take some rusty needles and poke them through the brain slowly. Stab out their eyes while doing this, so they can focus on the pain they are experiencing. To finish them off, use the claw side of the hammer and inject as hard into the brain as possible.
